I just had this issue: Error 310 (net::ERR_TOO_MANY_REDIRECTS): There were too many redirects (Chrome) and The page isn’t redirecting properly (Firefox). It came out of nowhere and I wasn’t able to log-in to my site.
Once I removed the plugin login-lock I was able to login without any other changes.
I added the plugin login-lock back and I couldn’t login.
Finally I just removed it, I’m looking for another plugin of the sort.
